Infection by bacterium Erwinia amylovora is one of the most serious problems in fruit growing, causing enormous damage leading to the deterioration of trees, even whole plantations. Fruit growers are not sufficiently aware about the importance of inoculum transfer thru pruning tools as the most common way of spreading the disease, especially within the same orchard. Laboratory research was carried out on three pairs of scissors. Two pairs were contaminated by laboratory-grown bacterium E. amylovora. All shears were rinsed with distilled water and it was further diluted. Dilutions were grown on a NA medium. Shears rinsed in time zero since contamination had a positive result on the culture medium. Rinsing shears, after they spent 24 and 48 hours closed in plastic bags, gave negative results. Shears that weren't contaminated during research gave positive results in the first two rinsings and showed negative results at the third rinsing. Smears of all mentioned shears after rinsing showed a presence of inoculum, regardless the rinse. After water rinsing the bacterial inoculum on shears is attenuated, but not eliminated, thus this measure is proved to be insufficient for shears decontamination.
